Previously, there are 2 members: TableScanParams and IncrementalRelation
in HMSExternalTable.
These 2 members are for Hudi's incremental query, so their lifecycle
should be with query task,
should not be saved in HMSExternalTable.
This PR mainly changes:
- Add LogicalHudiScan and PhysicalHudiScan, extends from LogicalFileScan
and PhysicalFileScan.
- Move TableScanParams and IncrementalRelation from HMSExternalTable to
XXXHudiScan.
- Add or modify related Nereids rules
